How many CFM for a range hood do I really need?

To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10. So, for a 42” electric stove you want a range hood with at least 420 CFM.

What is Broan HVI?

The Home Ventilating Institute (HVI) certifies the airflow and sound levels of range hoods according to a stringent testing and verification protocol. Broan HVI-certifies all of its range hoods so that you can trust the stated performance. This isn’t the case with every manufacturer, so be sure to look for the HVI certification on the package.

What is airflow test?

Airflow testing is conducted at a variety of static pressure points (i.e. essentially under a variety of potential duct system scenarios) from which a curve can be developed showing how much cubic feet per minute (CFM) of air a given model will move at different static pressure points. A typical curve looks like this (note that it can also vary by the ducting direction coming off the hood such as vertical vs. horizontal).

What is static pressure 0?

An alternative measure of airflow/power can be considered at 0 static pressure which is to say if there was no ducting attached to it at all . These CFM ratings will of course be significantly greater than a 0.1” reading. Many non HVI-certified brands appear to use a measure such as this. Broan defines this non-HVI-certified level as the “Maximum Power”.

What is the standard rating point for HVI?

HVI’s “standard” rating point is 0.1” of static pressure. This is the CFM airflow level traditionally shown on HVI-certified hoods and normally represents a typical, well-designed duct system.
